The full name of QSFP28 optical module is 100G optical module, which is one of the popular and mainstream 100G optical modules on the market. Due to its low power consumption and cost advantages, it has now become the main packaging method for 100G networks. At present, the QSFP28 optical module provides four different signals, and the transmission rate is increased from 25Gbps to 40Gbps. The size of QSFP28 optical module is smaller than other 100G modules, so it has received more and more attention and love. Especially our 100G QSFP28 bidirectional optical transceiver module has a longer life and higher performance, so it has been well received.

The QSFP28 optical module is mainly used in 100G Ethernet and EDRInfiniBand applications. It uses four 25Gbit/s transmission channels to transmit data, and the power consumption usually does not exceed 3.5W, while the power consumption of other 100G optical modules is usually between 6W and 24W. The mode is smaller than the CFP4 optical module, which means that the QSFP28 optical module has a higher port density on the switch.

As a kind of high quality 100G Optical Transceiver, the QSFP28 optical module is mainly composed of a first clock data recovery module, an array drive module, a laser emission module, a photoelectric conversion module and an electrical signal processing module. Converting it into an optical signal so that it can be propagated in the optical fiber has the advantages of transmission distance and transmission rate that cable propagation does not have. After reaching the destination, the optical signal is converted back to an electrical signal by the optical module for the device to use.

So how does it work? Let us briefly introduce: 1. First, the data recovery module will perform data recovery processing on the input 100G electrical signal, and then input the processed electrical signal to the array driver module; 2. The array driver module will perform data recovery on the received electrical signal. After modulation and demodulation, it is transmitted to the laser transmitting module; 3. In this part of the laser transmitting module, the electrical signal is converted into an optical signal, and then coupled into the optical fiber; 4. The coupled optical signal is transmitted; 5. Finally, through the electrical signal processing module, the electrical signals are sequentially converted into current and voltage, amplified and output to the main control terminal.
